印刷中紙張與之息息相關(guān)，紙張也分銅板紙、藝術(shù)紙，在印刷中紙張占據(jù)是一個大的費用，印刷廠對于紙張的存放也是一個關(guān)鍵的問題。

In printing, paper is closely related to it. Paper is also divided into copperplate paper and art paper. In printing, paper occupation is a big cost, and the storage of paper in printing factory is also a key problem.

紙張的保管是一項十分重要的工作，紙張在運輸過程中，切不可從高處向低處拋擲，以免發(fā)生散件和損傷，紙件切勿豎立儲運，應(yīng)當(dāng)一律平放，不宜在露天停放時間過久，要及時搬進車間或者倉庫。

The storage of paper is a very important work. In the process of transportation, the paper must not be thrown from high to low, so as to avoid the occurrence of loose parts and damage. The paper should not be stored and transported vertically, but should be placed horizontally. It is not suitable to park in the open air for too long. It should be moved into the workshop or warehouse in time.

紙張防潮，紙張對空氣的濕度非常敏感，紙張中的水份含量總是隨著空氣中濕度的變化而變化的。儲存紙張的庫房應(yīng)當(dāng)清潔，干燥，或者直接放在膠印車間里，紙堆要離開地面一段距離，要離開墻壁。儲放處的室內(nèi)相對濕度保持在60%-70%，而其室溫應(yīng)以18-22℃為適宜。

Paper moisture, paper is very sensitive to the humidity of the air, the moisture content of the paper always changes with the change of humidity in the air. Storage of paper warehouse should be clean, dry, or directly in the offset printing workshop, paper stack to leave the ground for a distance, to leave the wall. The indoor relative humidity of the storage place should be kept at 60% - 70%, and the room temperature should be 18-22 ℃.

紙張必須避免陽光直接曝曬，否則將因紙張中水份被蒸發(fā)而發(fā)脆、發(fā)黃，同時會使紙張變形上翹。如果變形那么無法使用印刷。紙張防熱。紙張不應(yīng)當(dāng)儲放在溫度過高的地方，當(dāng)一般紙張受到超過38℃的高溫時，其強度顯著降低，而且要翹曲變形，特別是銅版紙則會粘結(jié)成塊造成報廢。紙張防折，紙張儲存應(yīng)平攤堆齊，避免一折三疊那樣放置，堆放時，切不可使紙張的兩端交錯突出，否則突出部分容易變質(zhì)。

The paper must avoid direct sunlight exposure, otherwise it will be brittle and yellow due to the evaporation of water in the paper, and it will make the paper warped. If it is deformed, printing cannot be used. The paper is heat proof. The paper should not be stored in the place where the temperature is too high. When the general paper is exposed to the high temperature of more than 38 ℃, its strength will be significantly reduced, and it will be warped, especially the coated paper will be bonded into blocks, resulting in scrap. Paper folding, paper storage should be flat stack, avoid a fold three fold as placement, stacking, must not make the two ends of the paper staggered prominent, otherwise the protruding part is easy to deteriorate.

印刷用紙的厚度，緊度、平滑度、塵埃度，含水量，酸堿度及對平版膠印的影響，這些紙張的特性直接影響到印刷品的質(zhì)量，對上機印刷速度等都有影響。紙張的厚度均勻一致的話，上機印刷的質(zhì)量也就會更好。

The thickness, tightness, smoothness, dust content, water content, pH value of printing paper and their influence on offset printing directly affect the quality of printed matter and the printing speed. If the thickness of the paper is uniform, the quality of printing will be better.

平滑度，紙張的平滑度是需要紙張表面平整，光滑的程度，光滑了上機的速度也就可以暢通，提高印刷速度，印刷品也相對清晰。

Smoothness, the smoothness of the paper is the smoothness of the paper surface, smooth degree, smooth speed on the machine can also be smooth, improve the printing speed, print is relatively clear.

紙張是印刷的關(guān)鍵，印刷廠對于車間的溫度濕度都要控制，如需緊缺紙張可以囤貨，常用紙張不變的化，盡量庫存少，隨調(diào)隨用也可以減少資金壓力。

The paper is the key to printing. The printing factory should control the temperature and humidity of the workshop. If there is a shortage of paper, it can stock up. The price of commonly used paper should be kept unchanged, and the inventory should be as small as possible. It can also reduce the capital pressure when it is used.
